Abstract

The most important feature of 3D urban models is that different spatial information can be integrated and displayed in the same environment and also it is allowing complex urban models can be created and managed. 3D environments that contains land models, building models, vegetation models, transportation systems such as roads and city data that is based on geography can be shown with 3D virtual city models. For 3D buildings, the concept of scale is expressed by LoD (Level of Detail). Each LoD represents a specific generalization level. The main purpose of this study is; investigate the production of three-dimensional city models at different LoD levels required by all urban disciplines using point cloud data obtained from laser scanners. How to apply and, how to get a product at the end of integration will be discussed. The availability and usability of such data will be investigated on this paper. For this purpose, İnce Minareli Medrese, which is the symbol of Konya, was chosen. The result obtained from the study is a terrestrial laser scanner assisted three-dimensional structure model in which photogrammetric data is used in real scale

Özet

3B (Üç Boyutlu) kent modellerinin en önemli özelliği farklı mekânsal bilgilerin aynı ortamda bütünleştirilip gösterimine ve karmaşık kent modellerinin oluşturulup bunların yönetimine olanak sağlamasıdır. 3B sanal kent modelleri, arazi modelleri, bina modelleri, bitki modelleri, yollar gibi ulaşım sistemlerini içeren 3B ortamlar ve coğrafi tabanlı şehir verilerinin gösterimini içermektedir. 3B binalar için ölçek kavramı, LoD (Level of Detail) ayrıntı düzeyleriyle ifade edilmektedir. Her bir LoD belirli bir genelleştirme düzeyini gösterir. Bu çalışmanın ana amacı; kent tasarımı yapan tüm disiplinlerin gereksinim duyduğu farklı LoD seviyelerinde üç boyutlu kent modellerini, lazer tarayıcılardan elde edilen nokta bulutu verileri de kullanılarak üretimlerini araştırmaktır. Bu metodun nasıl ve ne şekilde uygulanacağı, yapılacak entegrasyon sonunda nasıl ve ne kalitede bir ürün elde edileceği gibi temellerin tartışılmasıdır. Bu sayede söz konusu verilerin kullanılabilirliği ve uygunluğu araştırılacaktır. Bu amaçla Konya'nın simgesi olma özelliğini taşıyan İnce Minareli Medrese seçilmiştir. Çalışma sonunda elde edilen model gerçek ölçeğinde fotogrametrik verilerin kullanıldığı yersel lazer tarayıcı destekli üç boyutlu yapı modelidir
